7 Factors to Consider When Choosing Photo Size

The largest digital photo ever taken sits at 3,200 megapixels. For comparison’s sake, the latest iPhone captures photos with 48 megapixels. And, you’d need over 300 4k television screens to display the picture at full size.

While you don’t need 3,200 megapixels to create an amazing image, it’s important to consider what you would need to optimize photo size for different situations. Resizing images is a simple process, but one small mistake can drop quality drastically.

If you’re curious about picking image size and the 7 most important factors to keep in mind for resized images, consider reading ahead.

Aspect Ratio

Aspect ratio refers to the width and height of an image. This is essential when choosing the screen or print used for displaying the image. If a screen, for example, can’t match an image’s aspect ratio, you have to crop the original image to fit it properly, lest you reduce its overall quality. If you must resize an image, consider using a picture resizer for better accuracy.

Distortion

Distortion is when lines or otherwise straight-edged objects are slightly warped. This comes into play when resizing images, of course. If possible, consider taking pictures at various angles to minimize distortion.

Color Accuracy

A ton of factors impact color accuracy. One of them, interestingly enough, is image size itself, where altering a picture’s overall height and width can change how colors are displayed. This is tied into how pixels work when displaying certain colors. The end result is either a product of eliminating certain parts of an image, or reconstructing them entirely.

Dynamic Range

Dynamic range refers to the capacity for camera equipment, and the software used to process the capture, to distinguish contrasting colors and the brightness in an image. The larger the range, the higher the quality of the image. This is more important for pictures that have large spaces occupied by varying shades of black and gray.

Sharpness

The importance of sharpness depends on the photographer and what’s being captured. But, it’s important to note that resized images typically have a very different level of sharpness from the originals.

Resolution

An image’s resolution is the amount of detail it can hold. Unlike aspect ratio, it has more to do with the number of pixels the output can display, and the number of megapixels a camera has. When resizing an image, the resolution will always change.

Image Compression

Compression is a great way to reduce the size of an image while maintaining as much quality as possible. The process essentially groups certain parts of the picture together. It’s highly recommended to use this technique when optimizing a website for speed.

Changing Photo Size

Photo size alterations can come with a few negative impacts on the original image. However, these are mostly unavoidable. The best thing you can do is keep these 7 factors in mind when taking the picture, transferring it to a device or cloud, and during the resizing image process.
